An inventory is about counting everything.
So write it as honestly as you can, and yes, include the good stuff too. It's hard to admit, but there is good stuff. (we not as bad or as good as we think....)
Anyway, if it's your first one, the "bad" side will likely be alot longer than the "good" side. But next time you do one, it will even out a bit.
Got a sponsor you can do this with?
